Perhaps we are fetishising physical things because our digital creations are social media junk food:

It’s easy to fetishize Brutalist buildings when you don’t have to live in them. On the other hand, when the same Brutalist style is translated into the digital spaces we daily inhabit, it becomes a source of endless whinging. Facebook, for example, is Brutalist social media. It reproduces much the same relationship with its users as the Riis Houses and their ilk do with their residents: focusing on control and integration into the high-level planning scheme rather than individual life and the “ballet of a good blog comment thread”, to paraphrase Jane Jacobs.
